This monitor checks whether the Distributed File System service is running.
The namespace server is offline because the Distributed File System service is not running.
The Distributed File System service is set to start Automatically, but is not running. A service can stop for many reasons, including:
The service was stopped by an administrator.
The service could not allocate the required memory.
The service was prevented from starting because the user account could not be authenticated.
Start the Distributed File System service
To start the service remotely by using the sc command, open a command prompt window and then type the following command, where <servername> is the name of the remote server:
sc <servername> start dfs
Note: To restart a service, you must be a member of the local Administrators group on the affected server.
Verification
This monitor resets to the Healthy state automatically after the service starts. To manually confirm that the service is started, type the following command:
sc <servername> query dfs
